WINDING ENGINE.

Application filed May 3, 1919. Serial 1%. 294,604..

To all whom it may] concern Be it known that we, .rinnxannnn Pamrnos,EDWIN M. Miionm, and Grosser-i. Heater, citizens of the United States,residing at Syracuse, in the county of Onondaga ano State of New York,have invented certain new and useful Improvements in Winding Engines, ofwhich the following is aspecification.

This invention relates to winding engines for use in any situationwherea rope, cable, or equivalent flexible connector is employed forperforming work such, for instance as hoisting, mine hauling, timberconveying, excavating and loading by scraper, &c., and particularly to awinding engine employing two drums adapted for independent drive,idling, and braking, but rendered,reciprocal or inter-related in suchoperations through means of a commoncontrol for their drivingconnections and a common control for their brakes, whereby either drumis adapted to be driven while the other drumis held stationary, or bothdrums may be left in neutral and free to revolve under the tension ofthe rope wound upon them.

The object of the invention is to provide convenient and eiiicient powerapplying and braking means affording a safe and reliable one-man controlfor such a winding engine, and. particularly a control that can beconveniently, safely, and efliciently manipulated in the restrictedspaces available in mine workings for machines ofthis class.

The invention will be fully understood upon reference to theaccompanying dlilW- ings showing one embodiment thereof selectedfor'purposes of illustration. In said drawings- Figure 1 is a plan viewof awinding engine embodying the several features of the presentinvention. I

Figure 2 is a longitudinal section of the same, with some of the partsin elevation.

Figure 3 is an elevation of the machine viewed from the controlling end;

Figure 4 is a side elevation of an intermediate portion of the, machineembodying the opposite ends of the winding drums with. their brakes, andthe gear wheel on the shaft lying between the drums through which theshaft is driven; and

Figure 5, is an end elevation of one of the hrakea General arrangement.

Upon a base 1 areerected end standards 2 and 3, and an intermediatestandard 4 in .which is journaled a mainshaft 5 with its driven gearwheel 6. Loosely mounted to rotateuponthe shaft 5 are winding drums 7and'z andfixedly mounted upon the shaft 5 at one end of each drum,preferably the outer end thereof, are driving clutches8, 8

each having controlling means comprising cones 9 moved in and out byshipping levers 11 mounted upon transverse rock/shaft 10 with actuatingrock armsll 11 coupled to move in unison by connecting rod 11, and allunder control. of the single manipulatlng means 12. The drums arefurther propulley driven from some suitable source.

Motor 16 in the presentinstance, has a circuit controller 17, comprisinga rheostat lever 17 and a reversing lever 17". Motor 16, in the selectedform, is connectedbyreducing gears 16, 16 driving theintermediate shaft16, and an additional reducing gear 16 meshing with the driven gearwheel 6 on the main shaft 5, as already described I ZH-tflfh control.

As best seen in Figures. 2 and 3, ach clutch consists of an expansionring 8? working internally upon the flange 7 of the drum, and anchoredintermediately at 8" upon one end of the clutch frame 8 which is keyedto the shaft 5 at 8 said expansion ring being connected at 8' near itsends to spreading levers 8 fulcrumed at 8? upon posts 8 adjustablysupported at one end of the clutch frame 8 so that movement of;

the levers toward the center of the shaft- 5 will expand the ring Swithin the flange 7'; said spreadlng levers having their free endspressed together, or in saidinward direc such that whenever left free toits own 210- tion, driving connectionlwill beestablished between theshaft 5 and the pulley 7 or 7 but this driving connection will befrictional in. its nature and adapted to overcome such amount of loadimposed upon the drum asis predetermined by the adjustment of thesprings 8 To release this friction clutch, levers 8 of each pair carryat intermediate points in their length, rollers 8 bearing upon thecorrespondingspreading wedge 9, which slides axially in the frame 8 ofthe clutch, and each of which is under control of its shipping lever 11on the shaft 10 as already explained so that when either shaft tro-lsthe arm 11" on the rock shaft 10 of the other clutch. I

Inasmuch as the clutches 8 and 8 are at different ends of the drums, thespreading wedges 9 will move oppositely in developing identical effectsin the respective clutches; in other words, they are reciprocal in theiractions when operated by the single controlling member 12, and one drumis thrown into driving connection as the other is thrown out. Bydetermining the length of the connection between the rock arm 11 and thearm 11 as, for instance,

by adjusting the turn-buckle ,11" which forms part of the connectingmember 11, the exact relation of the opposite movements of the spreadingwedges 9 can be determined; they can even be so related that when thecontrolling connection 11 is in an intermediate position both drums willbe free to respond to tension on the rope, and thus pay out any amountof rope that may be required in distributing it to the guide sheaves bywhich its direction will be controlled.

Reciprocat braking.

As will be seen from the drawings, the single control member 15 is inthe form of afoot lever, and the single control 14: for thebrakes is arock shaft upon which said foot lever is mounted, said rock shaft beingprovided at points properly related to the brake'bands 13, 13 with'arms14*, each receiving one end of one of the brake bands, the other end ofthe brake band being suitably anchored as at 13 in a known manner.

By positioning the arms 14 upon theshaft ll at 90 apart and reversingthe brake hands so that the anchoring end is presented horizontally inone instance and vertically in the other, while the tightening end meetsarm 14 vertically on one brake and horizontally on the other, it isobvious that rocking the shaft 14: in one direction will tighten thebrake on one drum and loosenit upon the other, and vice versa. It isalso obvious that by properly adjusting the lengths of the brake bandsthe shaft 14 may assume an intermediate position, in which both drumswould be free.

Coordination of bra/c2 12 g muldm'm'ng means.

vVith the described reciprocally acting single controls for both thedriving clutches and the brakes, and particularly by using one-mancontrolling means such as hand wheel 12 and foot lever 15, or theirequivalents, it will be seen that either drum may be thrown into drivenrelation to the main shaft,

while the other is left free to pay out rope in response to the windingaction of the driven drum, while both brakes are held re leased to leavethe drums free to respond to the influences acting upon them; or eitherdrum may be arrested in its rotation by application of the brakethereto, as for instance, when the driving connection is to be released,or when it maybe desired to retard the unwinding action of one drumwhile permitting the driving action of the other drum.

An important feature of the present invention resides in the fact thateach drum has a friction drive with means for prede-' terniining theload which it will carry, and. this friction drive is so constructedthat driving connection between the shaft and the friction member isdistributed over a plurality of circumferentially spaced points, namelyat an intermediate point in the friction member where it is firmlyanchored to one end of the clutch frame, and at the twocircumferentially removed fulcruining posts which are carried by theother end of the clutch frame and upon which the spreading levers arefulcrumed; and these fulcruming posts are separately and individuallyadjustable to insure the desired coaction between the friction memberand the drum. This enables the machine to be set for a predeterminedamount of work and insures yielding under an overload that will avoidbreakage in case an excessive resistance is encountered. It also insuresa distribution of drive between the friction member and the drum whichavoids chattering and other destructive influences which areparticularly important in an arrangement that provides for slippingunder an excessive load.

Another important feature of the present invention resides in theparticular arrangement of the clutch actuating and controlling mechanismwhich, while highly efficient in establishing a unitary control over adual arrangement of reciprocally acting winding drums, is peculiarlyadapted for use in a machine designed primarily for installation in therestricted spaces (in many instances not over three and one half feet inheight) in under ground workings; that is to say, by roviding a pair ofwedges moving in the direction of the axis of the shaft and in oppositedirections in the sense that one moves to clutch-applying position asthe other moves to clutch-releasing position and vice versa, bycontrolling these clutches through the medium of shipping leversswinging in planes parallel to the axis of the shaft from rock shaftsdisposed transversely across the ends of the respective drums; byproviding a pair of vertically extending controlling arms on the outerends of these transverse rock shafts; and by having a single thrustshaft extending longitudinally of the machine or parallel to the drivingshaft, connecting it with the pair of controlling arms, and thenproviding means which will afford the necessary power of control overthe thrust bar, a very eflicient and reliable control can be exercisedover the wedges without the necessity of extending leveragesobjectionably beyond the overall dimensions of the winding engine orrequiring increased space for the admission of the engine into the mineworking. By this arrangement the reciprocally acting wedges may be heldin neutral position permitting both drums to idle; by providing the turnbuckle or equivalent means for changing'the relation. between the wedgesand said body the spacing apart of the wedges and their initialrelations to their controlled clutches may be changed at will; and byproviding the adjustable stops upon the thrust rod the opposite throwsimparted to the wedges may be regulated at will.

Eaclradjustable frictional driving clutch 8 will preferably be enclosedby a housing 8" (shown only at the left hand end of Figure 1), whichwill avoid tampering with the adjustment by irresponsible operatives,and in order to maintain lubrication of the enclosed parts a suitablelubricator 8 may be employed.
